• How can I have the passphrase for a private key remembered for a user?

  - by Jon Cram

  I have a collection of web services running on Ubuntu Server 12.04 that pull code from a github repository. These services run under a specific user (let's call that user 'example'). In /home/example/.ssh/is_rsa is the private key associated with the relevant github account. When performing an operation such as git pull I am greeted with: Enter passphrase for key '/home/simplytestable/.ssh/id_rsa':. Enter the correct password and all is ok. The same private key is present on local development Ubuntu Desktop 12.04 machines and no passphrase is asked for. I'd like to be able to have the passphrase remembered so that upon entering it once it is never asked for again. This will aid in automating various web service updates. I'm guessing that the passphrase needs to be stored in the relevant user's keychain such that I don't have to enter it every time the private key needs to be unlocked. How can I achieve this?

• Confusion with Libgdx UI

  - by BrotherJack

  I've started with Libgdx and am currently stumbling about trying to understand how to set up the interface. I have generated the base projects in Eclipse ( < proj-name ,< proj-name -android, < proj-name -desktop, < proj-name -html), and can get the program to display a simple background, play a looping sound file, and draw a tank. I have been having some problems implementing the UI though. I want to make a collapsible interface bar at the bottom of the screen that would contain buttons for movement, and selecting weapons. I'm confused since there appears to be several ways of doing this and the documentation (or tutorials explaining it) tend to be obsolete. How would one go about this? Use a stage for the bar and actors for the widgets? I'm a little lost on this.

• Enabling DHCP without being connected

  - by Joe Philllips

  I was installing Ubuntu server the other night and I was not able to hook up to the network while installing because I don't have a monitor for my desktop machines. I had to go into the living room and connect to the HDTV instead. This leaves me without network connectivity. When installing it asks how I would like to set up the network. I would like to enable DHCP but it tries to detect a gateway when I do this and obviously it doesn't find anything. It won't let me move on without setting up an IP manually at that point. Isn't there a way I can enable DHCP for the next time it boots up instead? Why the need for it right then and there?

• Slow wifi with D-link DWA-160 A2

  - by Tommy Brunn

  I recently bought a USB wifi adapter for my new desktop computer. It's a D-link DWA-160 A2. From the start it didn't want to work at all, but after unplugging and then plugging it back in, it seems to work. However, my browsing is painfully slow. NetworkManager reports the connection to be at around 78-85% signal strength, which seems perfectly acceptable. Is there anything I can do to make it faster? I'm dual booting with Windows 7, where it seems to work fine, so I'm guessing that the problem occurs because of crappy drivers.

• USB-live does not save files between sessions

  - by Mads Skjern

  I created a USB-stick with Ubuntu, using the recommended tool "Startup Disk Creator" and the image for Ubuntu 13.10. The very simple interface looks like this: There can't be much to misunderstand in this GUI. I have chosen to create a USB stick with a live version of Ubuntu, which will save files and settings from session to session, on the USB drive, right? Well, it just doesn't save anything. I go in, create a file on Desktop, restart and it's gone. I did the whole procedure three times, i.e. first creating the USB, then testing if I could save. Have I misunderstood something?

• Can not get to login screen, background starts with terminal prompt only

  - by Doug

  my uncle has Ubuntu on his work PC. Basically I came in to work today, and he had lost his UNITY side bar. I told him start with just rebooting it. He rebooted it... now it does not even get to the login screen. It gets to the background with the word UBUNTU, and the 6 or 7 dots, does it's little loading dot thing... then stops, and a black terminal opens on the top left with the background still in place. Personally, I think he screwed it up himself. He always swears he didn't touch anything, but I know better... Either way, I can't get him back into the desktop to even see if the sidebar is back. He's always screwing around pressing the wrong buttons on the login screen, hitting admin things and such... Any ideas?

• List of Appindicators

  - by user8592

  I installed Ubuntu 11.04 on one of my systems and I am using Unity interface. Unity is working quite nice so far but i really miss panel applets for net speed, cpu temp, and system monitor. These applets show useful quickinfo and unlike 10.10 there is no way to get these on panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look. If you know then please list out any third party indicators with links so that they can be found at one place.

• Will Ubuntu 12.04 work on an Acer Aspire One D257-1682?

  - by Avid

  Is it possible to install Ubuntu 12.04 on an Acer Aspire One D257-1682? I have a disc that I used to run Ubuntu 12.04 on my desktop without incident. When trying to run it on my Aspire One, using an external DVD drive via USB, I get a ton of errors about missing files while it tries to load Ubuntu. I found a list of which versions of Ubuntu to run depending on which Aspire One model you have, but the D257 was not listed at all. I want to have Ubuntu on my Aspire One for coding Java and C++ since I don't have to sit at my desk for hours. Please help! -Avid

• How should I select continuous integration tool?

  - by DeveloperDon

  I found this cool comparison table for integration servers on Wikipedia, but I am a little uncertain how to rank the tools vs. my needs and interests. The chart itself seems to have a lot of boxes marked unknown, so if you are comfortable updating it on Wikipedia, that could be great too. Are there a few top performing products so I can quickly narrow down to four or five options? Which products seems to have the largest user communities and most ongoing enhancements and integration with new tools? Are the open source offerings best, or are there high quality tools that can be a great deal for a single user at home? Will use of multiple systems (primary desktop, local only home network server, personal and work notebooks, multiple virtual machines spread across all) create problems and how can they be managed?

• Getting vga_switcheroo with ATI Mobility Radeon 5650 HD to work

  - by stevejb

  Hello! I have a new HP dv7 laptop with ATI Mobility Radeon HD 5650 graphics card, and also Intel graphics (switchable). I have done the following and want to understand what is going on with my graphics driver Resized windows 7 and did fresh install of 10.10 Booted into 10.10 and things seemed to be working okay Enabled ATI graphics, and was clearly working on the ATI rather than Intel GPU (desktop cube worked) Rebooted, got an error that modprobe could not load modules.dep, and also something about i915 symbols Rebooted into recovery mode, modified xorg.conf to remove the mention of fglrx Rebooted, and the errors show, but then x starts but clearly in intel graphics I would ideally like to be able to switch between the ATI and Intel graphics, a la vga_switcheroo. My first problem seems to be that the folder /sys/kernel/debug/vgaswitcheroo does not exist, hinting at some kind of kernel issue. What can I do to get this available? Thanks!

• How To Play DVDs on Windows 8

  - by Chris Hoffman

  Upgrade to Windows 8 and you may be surprised to find that you can no longer play video DVDs. Unlike previous versions of Windows, Windows 8 doesn’t include built-in support for playing DVDs. Microsoft opted not to include DVD support because so many new computers – especially tablets and ultrabooks – aren’t coming with DVD drives. Microsoft pays a licensing fee for each copy of Windows that ships with DVD support. Note: You can still use data DVDs with Windows 8. This only applies to video DVDs. 6 Start Menu Replacements for Windows 8 What Is the Purpose of the “Do Not Cover This Hole” Hole on Hard Drives?

• Networkmanager in systray gone and sound not working after update 13.10

  - by rubo77

  After upgrading my Xubuntu 13.04 to 13.10 I have no sound. I still have sound if I start VLC with sudo mpg123 test.mp3 So it seemd there is a right problem EDIT after adding myself to the group audio with adduser myself audio I could play sounds again from the desktop with VLC But one problem remaining: The systray, usually looking like this: is not working anymore. No audio-settings and no network-manager in the taskbar in XFCE: there is just one small box with nothing in it. When I install stalonetray, There I see the status of wicd and all the other statuses, so the systray seems to be broken.

• What are the packages/libraries I should install before compiling Python from source?

  - by Lennart Regebro

  Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). Off the top of my head I can remember these: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) But I know there are many more. Please tell me and I'll update.

• How can I avoid the random restart of the xserver?

  - by Bernd

  I'm using a desktop pc with 64bit Ubuntu 12.04 (Kernel 3.2.0-24-generic). Hardware specs are - Intel Core i7 CPU 860 @ 2,80GHz x 8 - Nvidia GeForce GTS 250 - 750 GB Hard Disk ATA WDC WD7501AALS-00E3A0 (for my /home partition) - 128 GB Solid-State Disk ATA PLEXTOR PX-128M2S (for all other partitions) Since I reinstalled the PC with Ubuntu 12.04 the xserver restarts randomly. Most times when I watch a video in the browser (maybe a flash issue?) but sometimes the restart/crash appears when I'm working in an text-editor. How can I locate the problem? Which information is needed for a useful answer?

• How to Change the Window Border Size in Windows 8

  - by Chris Hoffman

  The window borders on Windows 8’s desktop are fairly thick by default, but they don’t have to be – you can customize the side of the window borders with an easy-to-use application or a quick registry tweak. You can shrink the window borders and make them fairly thin, just as they were on previous versions of Windows. Or you can increase the window border size and make them extremely thick, if you prefer.. HTG Explains: Does Your Android Phone Need an Antivirus?

• SOA Suite 11g (11.1.1.3): Creating a single server domain with SOA Suite and Oracle Service Bus func

  - by Chris Tomkins

  One of the major benefits of the latest version of the Oracle SOA products, SOA Suite 11gR1 PS2 (11.1.1.3) and Oracle Service Bus 11gR1 (11.1.1.3), is that both products depend on the same version of WebLogic Server 11g (10.3.3) and so can be installed in the same domain. If you are a developer building artifacts for both but with a laptop/desktop with limited resources then this is particularly useful, as you can install a single server domain (by default you get a domain with an admin server and multiple managed servers) which incorporates both sets of functionality. The viewlet below shows you how to go about creating such a single server domain, using the configuration wizard. Just click the Play button from the viewlet menu to start it. Note: As you have added all this functionality into a single server, it will take a few minutes to start up. As this is my first foray into the world of viewlets I’d be interested in your opinion as to whether you have found this useful and any tips/techniques for improving any future viewlets I may create.

• Disc Drives: An Endangered Species

  - by Jason Fitzpatrick

  More and more computers are shipping sans-disc drive leading many industry watchers to proclaim the optical disc an endangered species on its way out. Do you still use your drive or are you letting the disc go? CNN Tech reports on the trend: Apple’s new iMac, its flagship desktop computer, was released Friday. For the first time, it has no disc drive. This marks a trend that has already begun on some laptops, like Apple’s MacBook Airs, and of course with mobile devices like smartphones and tablets. “Over time, an optical disc will be as much of an historical curiosity as a floppy disk,” said Michael Gartenberg, a tech-industry analyst with research firm Gartner Inc. According to Apple, where sleeker, thinner designs are always en vogue, dumping the disc drive was a no-brainer.

• Ethernet on an Acer Aspire One D255E not working

  - by Dustin

  Ok very frustrated here, but hopefully can find an answer here. I have an Acer Aspire One netbook D255E. I installed 10.04 desktop edition via live USB, only to find out ethernet is not connecting. The thing is, I had installed previously 10.04 thru wubi as 30GB, but wanted more so did this install. With the Wubi install it worked great internet worked added LibO, mint menu ect. So I know it could work, and it works on Win 7(what little GB is left). I have ethernet enabled, and gave myself all permissions, but still not working. Thank you for any help, and if you do more details in the steps i need to take the better :).

• .pam_environment in kerberized nfs4 home directory

  - by Paul Stoever

  How can I get pam_env to read the user's .pam_environment file, if the user's file is located in a kerberized NFS4 mount? The file and directory permissions for the .pam_environment file are set in a way, that allows the local root to read the file. Reading .pam_environment only fails on the first login. Subsequent logins successfully read the file. The client uses Ubuntu 12.04 Desktop, NFS/Kerberos server is 12.04 Server. The Kerberos/NFS4 stuff works with exception of this. From /var/log/auth for first login: ... lightdm: pam_krb5(lightdm:auth): user USERNAME authenticated as USERNAME@REALM lightdm: pam_unix(lightdm:session): session closed for user lightdm lightdm: pam_env(lightdm:setcred): Unable to open config file: USERHOME/.pam_environment: Permission denied lightdm: pam_env(lightdm:setcred): Unable to open config file: USERHOME/.pam_environment: Permission denied lightdm: pam_unix(lightdm:session): session opened for user USERNAME by (uid=0) ...
